Well I guess we all live very different lives :)

I only bother with one phone plus an emergency backup because the only work things on my phone are a chat app and some authenticator codes.

For laptops, I wouldn't take any on vacation because I'm not working. I'd take the work one for work trips.

I very rarely use my personal laptop. I stream on my phone, if I want a bigger screen, I either cast or use the app on the TV. So for me it's work laptop and two phones, not bad at all for the peace of mind. I literally turn off work. I used to run mixed, and I really wish I had changed earlier.
